2.3.29 Counter with Flag
Yes or No
This parameter determines which variation will be returned for object 20 when
the master requests variation 0. If the parameter is set to N, variation 5 will be
returned. If the parameter is set to Y, variation 1 will be returned.
Note: Flag will always be set for Online and cannot be changed through by the PLC or user
program. Only the default variation returned by the module will be affected by changing this
parameter.
2.3.30 Frozen Counter with Flag
Yes or No
This parameter determines which variation will be returned for object 21 when
the master requests variation 0. If the parameter is set to N, variation 9 will be
returned. If the parameter is set to Y, variation 1 will be returned.
Note: Flag will always be set for Online and cannot be changed through by the PLC or user
program. Only the default variation returned by the module will be affected by changing this
parameter.
2.3.31 Time Sync Before Events
Yes or No
This parameter determines if events are to be generated by the module before
the time synchronization from the master unit. If the parameter is set to N, events
will be generated irrespective of the module's time sync status. If the parameter
is set to Y, events will be generated only if the module's time is synchronized.
2.3.32 Use Trip/Close Single Point
Yes or No
If you set this parameter to Yes, Trip/Close events will function like Pulse On
operations. Only one bit will be reserved in the DNP BO database.
If you set this parameter to No, the dual-point relay control database (Trip/Close)
is overlaid on the DNP Binary Output database of the module. Each DNP point
index sent will have an offset of point index times 2 into the database. The first bit
of the dual-point relay control database will correspond to the close relay and the
second will correspond to the trip relay.
The bit definitions from control byte of CROB are as follows:
00 - Null (single bit control or select of Trip/Close
01 - Close relay
10 - Trip relay
11 - Invalid
